I have installed a server with B-Translator at https://l10n.org.al, and it took me a long time to configure it properly with NGINX + MySQL + php5-fpm + apc + memcached + Drupal7, so I have tried to create a tklpatch in order to speed up the process of building another server similar to this. It is based on the NGINX appliance from: http://www.turnkeylinux.org/nginx-php-fastcgi
The patch is in github: https://github.com/dashohoxha/B-Translator/tree/master/tklpatch
However it is not working properly yet. I will try to fix it, but if somebody could help me to make it work, I would appreciate.
